1. A medical textile product comprising:
a textile substrate having opposed first and second surfaces, the textile substrate comprising a textile construction of one or more yarns;
wherein the second surface comprises a coating of a substantially water-insoluble, non-porous elastomeric sealant, disposed thereon;
wherein the one or more yarns at the first surface are pre-treated with a removable composition, which removable composition is substantially removed prior to use or implantation, such that the water-insoluble elastomeric sealant encapsulates a portion of fibers of the one or more yarns at the second surface of the textile substrate;
wherein the textile substrate is substantially impermeable to fluid; and
wherein the first surface is substantially free of the substantially water-insoluble elastomeric sealant.
